    Design, development and testing of a batch type solar copra dryer
    (2007-02-08) Jaswant Singh; Nambiar, K.K.; Nambiar, C.K.B.
    Solar Copra dryer for capacity of 150 coconuts per batch was designed developed and tested. It saved 44 per cent of total drying time, in bringing down the moisture content of Kernel from 53.10 per cent (w.b.) to 6.2 percent (w.b.), compared to open yard drying. The drying cost per 100 nuts was Rs. 3.4S for solar dryer as against Rs. 6.67 for open drying.

    Development of an improved tray type mechanical copra dryer
    (2007-02-08) Patil, R.T.; Jaswant Singh
    For drying the copra in rainy season without affecting the quality a tray type (mixed flow) mechanical dryer was develo-f ped at Central Plantation Crops Research Institute, Kasaragod, India. Electricity being the cheapest and no necessity of indirect heating ; was used as energy source. The dryer was fabricated from the materials such as wood, GI sheet, AC sheet, Asbestos rope and MS sheet. ;'- Components of the dryer were drying chamber, air distribution unit, plenum chamber, heating unit and blower. Drying chamber accomoda-X ted air distribution unit in the centre with copra trays on its both sides. The air was blown by 1.5 hp motor operated blower on 8 kW hea-[ lets. This hot air then was circulated through the material on the trays. The capacity of dryer was 1,000 nuts per batch and drying time I required was about 30 hours. The cost of the dryer was worked out to be Rs. 8,000 — and the cost of drying came to about Rs. 0.58 per kg
